Taught to think big by her father who was a mapmaker, Marie wanted to do something no one had ever done before: map the bottom of the Atlantic Ocean. Was it even possible? Not sure if she would succeed, Marie decided to give it a try.Throughout history, others had tried and failed to measure the depths of the oceans. Sailors lowered weighted ropes to take measurements. Even today, scientists are trying to measure the depth by using echo sounder machines to track how long it would take a sound wave sent from a ship to the sea floor to come back. But for Marie, it was like piecing together an immense jigsaw puzzle.Despite past failures and challenges—sometimes Marie would be turned away from a ship because having a woman on board was “bad luck”—Marie was determined to succeed. And she did, becoming the first person to chart the ocean floor, helping us better understand the planet we call home.

    On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?
